The cost of the plate itself is higher than other slate fixing solutions on the market but the positive impact it has on installation time heavily out ways the additional cost of the product itself. The 3 installations(total 25.5kW) were installed in 3 days by 2 panel fitters so a substantial saving was made on the installation costs. The benefits of this product for us are listed below: Some metal fixings are flimsy. Others take too much time, are awkward to prepare, and if wrongly prepared the head of the slate could slip off the upper batten. Stainless Steel Slate Hooks are an alternative fixing to clout nails for fixing Natural Slates, which is used extensively across Europe. This method offers a cost effective alternative method with lots of bonuses. Hooks can be used in the most exposed locations and because the slate is supported at four points, the resistance to wind uplift is extremely effective. The top edge of the slate is gripped under the top part of the hook. The shank of the hook runs down along the side of the slates in the next course, and the return grip at the bottom of the hook holds the tail of the slate on top. This means that each slate is held in place by four hooks; one at the head, one at the tail and one on each side. The one at the tail stops the hook from sliding down, the ones at the side prevent it from turning and the one at the head holds it at the batten.
All natural slates can be fixed using slate hooks. The hook method offers considerable freedom in design and can save up to 25% on labour costs and eliminate breakages. The practice is very popular in Europe and is gaining popularity in the UK.

Firstly, put the hooked end of the slate ripper underneath the damaged slate, trapping the nail in the hook. Then hammer the handle of the slate ripper, to force the nail out of place. Now the roof has been set out correctly, with the battens at the right distance apart, it’s time to lay the slates. Start by laying the under eaves course, creating a staggered pattern for stability – a 5mm gap between each slate is required to allow for natural expansion. After receiving an instruction to proceed with a 33.35kW solar PV installation upon 4 roofs of a private estate, we wanted to find a more cost effective solution for installing the mounting system to the 3 slate roofs in the project.
Firstly, ensure your rafters or trusses are clean of any splinters or old nails that could damage the membrane. Then roll your chosen roofing membrane along the roof trusses – start from one bottom corner and roll it along to the other corner. Once the membrane has been rolled out, use clout nails to secure one edge. Then pull the membrane taut at the other end, and fix it into position, before adding a few more nails across the membrane where it meets the timber trusses for extra stability. 5. Batten placement In centre-nailed slating, the gauge is the spacing at which the battens are fixed to the rafters, trusses or counter-battens to provide the required head-lap. The margin is the exposed length of the slate measured in the same direction as the gauge. The lap and margin will be the same.

Although the traditional method of slating a roof uses hooks, this can be time-consuming and complicated. Therefore, in this guide, we will be outlining how to slate a roof using pre-drilled slates. A recycled roof slate is the result of combined waste slate materials. This goes even further regarding the environmental impact as there is no manufacturing process involved in the creation of the final project. In turn, this means that the amount of wastage is reduced. I’ve chosen what I want for my slate roof, what’s next? Firstly, find out if your slates are pre-holed. If they aren’t you’ll need to pierce two holes into the slate, one either side of the short width, approximately a third of the way up the length of the slate. To do this, you can use a number of cutting and holing tools. 1. Find out the pitch of your roof
The man-made roof slate is considered more eco-friendly for consumers. However, despite their development process taking a more modern approach, their look doesn’t steer far from the traditional slate appearance. Due to their manufacturing, they also have a greatly reduced risk of breaking. Recycled roof slate With a bright stainless steel coating for a purely decorative finish, this coating does not impact the corrosion resistance of the core material. The bright finish will typically last ten years or more unless in very abrasive settings for example salted winds. The Hall Hook is a permanent, secret and fail safe device that should be used when replacing a broken slate. Clenergy C3 Self-drilling Universal Screw, Buildex 14-11 x 70 Hex Head Zips Datasheet V2.1 – US-6.3 70-BW BX Suitable for fixing roofing slates on a roof application, these slate hooks are an ideal alternative to the copper nail. Manufactured from 316-grade stainless steel, these hooks are guaranteed in severe coastal exposure conditions in front of the sea or industrial environments.The British Standard Code of Practice (BS 5534) specifies two ways of installing slates: nailing or hook fixing. These fasteners fix the slates to either batten, which is by far the most common English method, or to sarking board, which is commonly used in exposed areas in Scotland. If you are looking for a cost-effective alternative to copper nails yet still comply with British Standard, alloy clout nails are an excellent choice. These nails have been specifically manufactured for use on natural slate roofs and will protect your roof from nail fatigue. Stainless Steel Slate Hooks
e) Add a third batten, sliding it from the top downwards to below the top of the slates. Make sure that the top of the full-sized slate is sitting central to the batten. Fixing SIGA slates is straightforward for an experienced slater. Most SIGA slates come pre-holed at a nominal 90mm headlap. By simply moving the location of the slate on a standard 50x25mm batten, these can be fixed to obtain headlaps between 76 and 96mm, allowing them to be used on a variety of pitches. Nailing Natural Slates There are two type of Slate Hook, an over batten type and a drive in type. The use of over batten type is very limited with the majority being drive in type (shown in picture).

Roof slates are a very popular choice when it comes to deciding which roofing material to use on a pitched roof. As well as being aesthetically pleasing, and increasing the potential selling value of the house, roof slates have a number of physical benefits. Slate is a durable and hard-wearing material that provides waterproofing characteristics to a pitched roof, unlike other roof materials which absorb water. This means that slate is unaffected by frost damage and freezing. What types of slate roof are there?
